Breaking: US Indo-Pacific Command drops the “Indo” and reverts back to its original name: US Pacific Command

Here is a tutorial for uninitiated for QR for those wanting to enter the competition. All you need to know is a little bit of algebra. Here @ means matrix multiplication. Let A be a 3 x 3 matrix and task is given A can you find Q and R. A special property of Q is that Q @ Q.T = I and R is a upper triangular matrix: A find Q and R. Q @ R = A [ [0, 1, 0], [ [2, 3, 4], [ [0, 5, 6], [1, 0, 0], @ [0, 5, 6], = [2, 3, 4], [0, 0, 1] ] [0, 0, 7] ] [0, 0, 7] ] The R matrix has a special property: [ [2, 3, 4], [0, 5, 6], [0, 0, 7] ] We are generally fine with any R matrix with this structure, see the zeros on the lower triangle. [ [0, 5, 6], A = [2, 3, 4], [0, 0, 7] ] First column of A: [ [0], x = [2], [0] ] Householder matrix: [ [0, 1, 0], H = [1, 0, 0], [0, 0, 1] ] Now compute Hx: [ [0, 1, 0], [ [0], H x = [1, 0, 0], @ [2], [0, 0, 1] ] [0] ] [ [2], = [0], [0] ] Now how do we get H? Well it turns out these are called reflectors. The householder reflectors. Think of putting a mirror on your vector.

The Army in question 😂 (This clip features former Pakistani dictator and Army Chief Pervez Musharraf, pleading with US senators to allow him to continue his government, promising to be a loyal dog.)

Show me the GSQR. Am not talking of Project Definition under Mission Mode. Please sir.
